需要帮助格式化PHP中的目录列表的结果,javascript树控件

标签: php javascript jquery html

我正在尝试使用PHP列出一个特定文件夹中的所有文件夹和文件。使用下面的代码,我设法列出一个长列表中的所有文件和文件夹。现在我真正要做的就是列出它们,以便我可以使用HTML / jquery将目录结果显示为文件夹旁边带有+标记,这样它们就可以扩展,但我无法弄清楚如何格式化结果PHP就是为了做到这一点。

 include('include/class.dirlist.php');
 $resources = "/Inetpub/companyweb/resources";
 $dir = getDirectoryListing($resources,"a",1,1,"all",1);

 $i = 0; //for illustrative purposes only 
 foreach ($dir as $item) {
     echo "<b><a href='resources/".$dir[$i]."'>".$dir[$i]."</a></b><br>";
     $i++;
 }

上面的代码将输出如下内容:

FOLDER1
FOLDER1 / FILE1.PDF
FOLDER1 / FILE2.PDF
FOLDER2
FOLDER2 / FILE1.PDF
FOLDER2 / FILE2.PDF

以下是我对以下评论的回复: @ hek2mgl这正是我想要做的。我想树型视图。

@popnoodles如果我能把它变成“ul li”格式,那就是我相信我可以使用的东西。问题是,我是初学PHPer ...所以在这里寻找一个有效的解决方案。

@BjørneMalmanger以下是所包含课程的内容:

function getDirectoryListing($dirname, $sortorder = "a", $show_subdirs = 1,         $show_subdirfiles = 0, $exts = "all", $ext_save = 1) {
// This function will return an array with filenames based on the criteria you can set in the variables
// @sortorder : a for ascending (the standard) or d for descending (you can use the "r" for reverse as well, works the same)
// @show_subdirs : 0 for NO, 1 for YES - meaning it will show the names of subdirectories if there are any
// Logically subdirnames will not be checked for the required extentions
// @show_subdirfiles : 0 for NO, 1 for YES - meaning it will show files from the subdirs
// Files from subdirs will be prefixed with the subdir name and checked for the required extentions.
// @exts can be either a string or an array, if not passed to the function, then the default will be a check for common image files
// If exts is set to "all" then all extentions are allowed
// @ext_save : 1 for YES, 0 for NO - meaning it will filter out system files or not (such as .htaccess)

if (!$exts || empty($exts) || $exts == "") {
   $exts = array("jpg", "gif", "jpeg", "png", "doc", "xls", "pdf", "tif");
}
if ($handle = opendir($dirname)) {
   $filelist = array();
   while (false !== ($file = readdir($handle))) {

       // Filter out higher directory references
       if ($file != "." && $file != "..") {
           // Only look at directories or files, filter out symbolic links
           if ( filetype ($dirname."/".$file) != "link") {
               // If it's a file, check against valid extentions and add to the list
               if ( filetype ($dirname."/".$file) == "file" ) {
                   if (checkFileExtention($file, $exts, $ext_save)) {
                                   $filelist[] = $file;
                   }
               }
               // If it's a directory and either subdirs should be listed or files from subdirs add relevant names to the list
               else if ( filetype ($dirname."/".$file) == "dir" && ($show_subdirs == 1 || $show_subdirfiles == 1)) {
                   if ($show_subdirs == 1) {
                       $filelist[] = $file;
                   }
                   if ($show_subdirfiles == 1) {
                       $subdirname = $file;
                       $subdirfilelist = getDirectoryListing($dirname."/".$subdirname."/", $sortorder, $show_subdirs, $show_subdirfiles, $exts, $ext_save);
                       for ($i = 0 ; $i < count($subdirfilelist) ; $i++) {
                           $subdirfilelist[$i] = $subdirname."/".$subdirfilelist[$i];
                       }
                       $filelist = array_merge($filelist, $subdirfilelist);
                   }

               }

           }
       }
   }
   closedir($handle);

   // Sort the results
   if (count($filelist) > 1) {
       natcasesort($filelist);
       if ($sortorder == "d" || $sortorder == "r" ) {
           $filelist = array_reverse($filelist, TRUE);
       }
   }
   return $filelist;
  }
  else {
    return false;
 }
 }

 function checkFileExtention($filename, $exts, $ext_save = 1) {
 $passed = FALSE;
 if ($ext_save == 1) {
   if (preg_match("/^\./", $filename)) {

看看jstree。我想这就是你想要的。 (我是用jstree完成的)。 Jstree是一个javascript库,可以使用控件将HTML列表(<ul>, <ol>)或json或xml等树结构渲染为带有“+”的可控树,以打开和关闭您希望的文件夹。

当然jstree只是javascript的一部分。您必须将getDirectoryListing()的输出格式化为jstree支持的格式之一。目前这是

  • 的Json
  • XML
  • HTML

这是一个基本的例子。当finiehd看起来像这样:

finished example in browser

您可以使用树打开和关闭节点。

我已将您的目录列表功能更改为为jstree生成JSON的功能。它实际上源于此SO post以使事情快速起作用。谢谢! :)这是php。将其放在网络服务器的一个文件夹中,并将其命名为tree.php

<?php

header('Content-Type: application/json');
echo json_encode(dir_to_jstree_array(__DIR__));

function dir_to_jstree_array($dir, $order = "a", $ext = array()) {

    if(empty($ext)) {
        $ext = array (
            "jpg", "gif", "jpeg", "png", "doc", "xls", "pdf", "tif"
        );
    }

    $listDir = array(
        'data' => basename($dir),
        'attr' => array (
            'rel' => 'folder'
        ),
        'metadata' => array (
            'id' => $dir
        ),
        'children' => array()
    );

    $files = array();
    $dirs = array();

    if($handler = opendir($dir))
    {
        while (($sub = readdir($handler)) !== FALSE)
        {
            if ($sub != "." && $sub != "..")
            {
                if(is_file($dir."/".$sub))
                {
                    $extension = pathinfo($dir."/".$sub, PATHINFO_EXTENSION);
                    if(in_array($extension, $ext)) {
                        $files []= $sub;
                    }
                }elseif(is_dir($dir."/".$sub))
                {
                    $dirs []= $dir."/".$sub;
                }
            }
        }

        if($order === "a") {
            asort($dirs);
        } else {
            arsort($dirs);
        }

        foreach($dirs as $d) {
            $listDir['children'][]= dir_to_jstree_array($d);
        }

        if($order === "a") {
            asort($files);
        } else {
            arsort($files);
        }

        foreach($files as $file) {
            $listDir['children'][]= $file;
        }

        closedir($handler);
    }
    return $listDir;
}

这里有基本的HTML和javascript。给它一个正确的名称并将其放在tree.php旁边。我正在使用jstree的json_data插件和ajax。此外,我正在使用类型插件为文件夹和文件呈现不同类型的图标。 (如果需要,也可以为每种文件类型设置一个自定义图标)。你必须在html文件旁放置一个正确的folder.png和image.png。

<html>
  <head>
    <script type="text/javascript" src="jquery-1.8.3.min.js"></script>
    <script type="text/javascript" src="jstree-v.pre1.0/jquery.jstree.js"></script>
    <script type="text/javascript">

        $(function() {
          $('#dirtree').jstree({
            plugins : ["json_data", "themes", "types"],

            json_data : {
              ajax : {
                'url' : 'tree.php'
              }
            },

            'types': {
              'types' : {

                'folder' : {
                  'icon' : {
                    'image' : 'folder.png'
                  }
                },

                'default' : {
                  'icon' : {
                    'image' : 'image.png'
                  },
                }
              }
            }
          });
        }); 

    </script>
 </head>
 <body>
   <div id="dirtree"></div>
 </body>
</html>

多数民众赞成! :)请注意,您有许多配置选项,样式选项和jstree插件。你当然会扩展我的榜样。
